ELECTRIC SWITCH Application filed December 6, 1917. Serial No. 205,863.

lb all whom it may concern:

Be it known that I, J OHANN G. PETERSON, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Electric Switches, of which the following is a specification.

This invention relates to electric switches. While the improvements, and there are several, are susceptible of incorporation -with utility in switches of difi'erent kinds, they are. of prime advantage, however, when enibodied in a pendent switch. Among the objects of the invention are the provision of a r-article of the character set forth which is s mple in construction, quite com )act, and

positive and certain in action. Tie device comprises other features of novelty which with. the foregoing will be stated at length in the following description, wherein I will set forth in detail that form of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. I do not necessarily limit myself to this particular disclosure; I may depart therefrom in several particulars within the scope of the invention defined by the claims following said description.

Referringto said drawings:

Figure 1 is an elevation of a switch com:

1 the chamber 8.

Figs. 1 and 2. The two parts 3 and i may be unltedtogether in any desirable manner. For this purpose I have shown the screws 5, two of them generally being provided and being superposed, the section 4 having bores as 6 for the passage of the screws and the section 3 having internally threaded sleeves 7 ordinarily molded therein, to receive the threaded portions of the screws and thus hold the two parts 3 and 1 .in assembleu relation. It becomes a simple matter to separate the parts, and this is accomplished by backing out the two screws to the requisite extent. The heads of the screws 5 are ordinarily countersunk in the body section 4.

lVhile either of the sections of the supporting body may be equipped with wire connecting and contact means, the part 3 in the structure illustrated is thus provided, and I will now set forth how this is done. Said part 3 has as shown a chamber or compartnient 8 into which the complcmental apertures 9 open, the upper opening 6 to which I have already referred, extending through the web 10 between these apertures 9. In the apertures 9 are disposed the plates 11 which in the present case .do not engage directly against the bottoms of the apertures as I will hereinafter explain. hThcse plates 11 areperforated to freely receive the screws 12, which are threaded into sleeves 13 molded in the composition of the part 3, the inner terminals of the sleeves 13 being expanded as at I-t to anchor the sleeves firmly in place. The outer faces of the sleeves are in the plane practicail oi' the bot! nus of the aper tures, the plates n-acticallr extending into etween the plates 11 and the bottoms of the apertures 9 are disposed the comparatively thin plates 15 which extend down into thechambcr or cavity 8 and Y rated to receive the screws 12', and they fit under the wire connecting plates 11 whibh clamp them respectively as a consequence to the bottoms of the apertures 9 and chamber or cavity 8. The wire connecting plates 11 have ta ped openings to receive the screws 17 which extend through perforations in the respective contact plates 15 and into sockets 18 in the part or section 3. Thus the contact plates 15 are in electrical connection with the respective wire connecting plates 11. The wires 18 extend through an opening 19 in the top of the body 2 and are wrapped or coiled one or more times about the b0 ies of the screws 17 which bind the bared parts of the wires against the plates 11. In view of this circumstance, it will be clear that when the contact plates 15 are bridged by the electrical connection of the s ring fingers or contacts 16, the switch will e in the on relation. This condition is shown in fact by dotted lines in Fig. 2.

The switching mechanism includes in its organization a support such as that denoted in a. general way by 20. This su )port or bracket has a body 21 practically at from the ends of which are the pendent pro ections or flanges 22 and 2 3, the flange or projection 22 being a trifle longer than or deeper than the companion promotion and fittmg an aperture 24 extending from the chamber or cavity 8. The attaching flange 22 asshown is perforated to receive the screw 25 in threaded engagement with the sleeve 26 molded into the section 3, the inner end of the sleeve being expanded or s read as described in connection with the sleeve 13. The outer face of the sleeve 26 is practicall flush with the aperture 24, and it will in clear that the head of the screw 25. inds the flange or foot 22 solidly and subs tttiall against the bottom of the a eiture,-the si e walls thereof preventing tip of the flange or foot 22 and hence of the sup rt or bracket 20. The section 4 of the )ody has a chamber or cavity 8 complemental to the cavity or chamber 8 and from the cavit 8' there extends the aperture 24' against t e back of which the flange or foot 23 fiatwise bears, the lower edges of the flanges 22 and 23 being contiguous to the bottoms of the apertures 2i and 24. From the aperture 24 extends the recess 26 and through this projects the lower screw 5 which I have already described, the solid portion of the member or part 4 closing this recess 26' and the lower portion of the aperture 24.

'The switching member is denoted in a nerai way by 27 and practically speaking it is of bail or inverted'form, its si( es having at their lower ends the outwardly projecting pintles 28 which fit openings 29 in the cheeks 30 which risefrom the base 21 and necessarily form a part of the support or bracket 20. The switching member 27, therefore, rocks between the cheeks 30 which are provided at their sides with extensions 31 provided with inward projections 32, said projections constituting suitable stops to arrest the switching member when in the on and the 011 positions. In Fig. 5 the switching member is shown in the oil position and atthis time abuts against the two projections 32 on the right. \Vhcn in the on posi tion as shown by dotted lines in Fig. 2, the switching member will be against the cooperating projections 32 at the left in said Fig. 5.

The actuator for the switching member is denoted in a general way by 33 and it comprises a body as 34 and buttons as 35. The body 34 is of yoke-form, and it con ists as illustrated of a main portion )rovided with upwardly extending termina s which have threaded holes to be engaged by the screws 36, the shanks of which are molded in and the threaded parts of which extend inwardly from the buttons to fit the said threaded holes at which time the inner ends of the buttons will practically solidly en-- gage the upstanding portions of the connecting or yokc-likc body 34. The actuator 33 is carried for sliding movement by the support or l'u'ackct 20 which has a slot as 37 entirely across to provide for the guide connection ofthe body 3% with said support, the base 21 having flanges 38 extending toward each other and overlying the bottom or main portion of the body 3i to thus ac-- cnratcly guide said body which forms a rigid part of the actuator 33 in its respective movements. TlllS also provides a.

proper way of connecting the actuator 33 with its support 20. F

The transverse portion of the switching member 27 is provided practically centrally thereof with a depending projection 39 to which is connected one end of the coiled spring l0, the other end of said spring being connected with the loop ll staked from the main or bottom portion of the body 34. The transverse portion of the spring in addition has the complemental contacting portions -12 on the upper portions of its sides. The sections 3 and 4 of the body of the switch have perforations or openings as 43 to receive the buttons 35, the two openings 43 being coaxial and their inner portions receiving the upstanding parts of the main portion 34 of the actuator when in the res uective positions thereof.

n Fig. 2 the full lines show the parts in the oil position. To close the circuit, the

following procedure will be adopted: The

will instantly snap the switching member 180 27 to the on or dottedlinc position so as to carry the contact portions 42 between the two spring contacts 43 as shown practically by dotted lines in Fig. 2. To open the circuit the action just described will be reversed.
